The platen l is supported'upon a shaft 2 Whieh is moonteo'. in a paper carriage 3 superimposed and operating upon a suitable carriage support embodied in the machine. The plaaen shaft is provided with knobs 4 for manual rotation and adjustment.

she-it 5 is supported in the platen cerriage below end parallel with "the platen and at suitable intervals is provided with grooves 6. In thegrooves 6 the bifurcated 3 is sectional ends of em rearwerlly extending arms 7- are seated. The arms Zero, arranged in pairs and each pair of arms supports a pressure roll 8, the series of pressure rolls 8 being axially alined and adapted to cooperate with the platen to serve as the rear pressure rolls in feeding the paper. One part of the space in the fork of each of the arms 7 is somewhat extended as indicated at 9, (Ifig.

3) so as to provide a surface for a camming action of the shaft 5 whereby said shaft 5 'willdepress the rear ends of the arms 7 to carry 'the rolls 8 out of contact with the platen. The shaft 5 is provided with notches 10, in effect being deeper cuts or depressions of the grooves 6 and being arranged to receive the cam portions 9, therepressure rolls 8 will be removed from the platen, as illustrated in Fig. 3.

Forwardly extending curved arms 13 are seated in grooves l t in the shaft 5 and have rear extensions 15 projecting over the rod 12. The grooves 14 are provided with deepened portions 16, similar to the deepened portions 10, normally receiving cam surfaces 17 on the lever 13,- similar to the cam surfaces 9 on the levers 7. In the normal position of the shaft 5 the cam and surfaces 17 are seatedin the deepened notches 16, just as the cam portions 9 are normally seated in the deepened notches 10. The arms 13 are also arranged in pairs, preferably being one pair of arms 13 for each pair of arms 7, and axially alined pressure rolls 18 are supported between the front ends .of said arms 13. Each arm 7, inthe' embodiment shown, is connected to the corresponding arm 13 by a spring 19, so that normally the rolls 8 and 18 are yieldingly retained in contact with the platen. Obviously, when the shaft 5 is turned to a position such as illustrated in Fig.3 the rolls 8 and 18. will be moved out of contact with the platen.

A lever 20 (Figs. Q'and 5) is attached to the shaft 5 and is connected by a link 21.

with the lower end of a lever which is pivoted upon a support 23 in the carriage. The upper end of the lever is provided with a handle 24 for manual engagement.

By operating the lever 22 to the position,

shown in Fig. the shaft 5 is turned and performs a'can'uning action upon all of'the lovers 7 and all of the levers 13, thereby depressing the presshre rolls carried by said' levers out of contact with the platen and permittmg movement and adpistment of the paper.

A paper table is supported in an oblique position in the carriage at the feedingin side of the platen and is arranged to receive and support the paper passing to the "platen. A rod 26 is supported in the car riage adjacent to the lower edge of the paper table 25, and a plate 27 has its rear upper edge pivotally engaged upon said rod. The plate 27 constitutes aseparately adjustable continuation of the paper table 25 and is curved under the platen concentrically with the platen and with the platen shaft 2, so that the .paper passing from the paper table 25 will be received by the plate 27- and thereby guided under the platen and directed to the feeding-outside of the platen. The portion of the plate 27 which is under the platen is yieldingly supported by the springs 19, so that when said springs are retracted to hold the pressure rolls 8 and 18 in contact with the platen, said plate 27 will be held adjacent to the platen, leaving sufiicient space, however, for the passage of the paper as illustrated in Figs. 2 and 6. In manifolding, or in passing thick or doubled portions of the paper around the platen the plate 27 will ,yield to give the necessary room for the paper, by pressing upon and' bending the supporting springs 19. 'Said plate 27 is provided with slots or openings 28 through which the feed rolls extend and operate against the platen. Thus, the plate 27 Will yield for manifold work or fordoubled or thick portions of the paper Without interfering with the free operation of the pressure roll, and vice versa.

, At suitable intervals the shaft 5 is provided with grooves 29 (Figs. 6 and 7), which form flat portions on the shaft. A

paper stop-arm 30 is mounted upon each of the flat portions formed by the grooves 29, said arms being under control of springs 31 whereby the rear ends of said arms are actuated toward the platen. In the'normal position of the shaft 5, that is, when the pressure rolls 8 and 18are in cooperative engagement with the platen, the edges of the flat portions formed by the grooves 29 engage against fiat parts of the stop-arm 30 and hold the rear ends of said arms depressed and out of contact with the platen and out of the. path of movement of the paper, in opposition to the springs 31. When the shaft 5 is rocked, by manipulation of the lever 22, the arms 30 are released from restraint by said shaft 5 and the rear ends of said arms are actuated against the platen, passing through slots 32 provided for that purpose (Figs. 5, 6 and7). Thus, simultaneously with the release of the pressure rolls the arms 30 are moved into en-- ga'gcment with the platen below the, pres sure rolls 8 and rearwardly from the pres; sure rolls 18. The upper ends of the arm .30 are provided with notches or paper seats 33 adapted to receive the front'ends Bil is ,era

aged by the paper feeding mechai'iisin, and

znay be accurately adjusted before being on gaged thereby. After the sheets of paper have been acc rately located and adjusted the lever 2-5.2 is returned to its normal position, as a result of -Wl11Cll the pressure rolls 8 engage the accurately adjusted sheets of.

paper, the arms 30 are moved out of the path of the paper, and the guide plate 2? assumes its proper position to guide the paper under the platen to the rolls 18. From the, foregoing it will be understood that the entire paper control ,mecl'ianisin, including the paper guide plate, pressure rolls, and the devices for positioning and adjusting the paper, are controlled by inanipulation of a single lever; so that, as an incident to the release of the pressure rolls, the paper positioning and adjusting devices are moved into position to be e guged by the paper without any special attention by the operator, Also, as the pressure rolls are engaged against the paper, the paper positioning and adjusting devices are automatir cally moved out of the path of the paper, so that the paper can pass freely under the platen. lit will be observed that as result of the arrangement of the arms 7 and upon the shaft 5, and the arrangement of the arms 30 upon said shaft an important timing of their operations is effected, so that the pressure rolls 8 will engage the paper before the arm 30 are released from the paper. This may be understood. by reference to Figs. 2 and 3, and a comparison thereof- With Fl 's. 6 and 7 in which it will x b 1 w l be observed tnat as the snaft 1S rocked to permit the pressure rolls 8 to engage the paper, the arms are not operated or dieengaged frointhe paper until after the rolls 8 have engaged the paper. 'lll'iereupon by a slight further inovei'nent of the shaft 5 the arms 30 are disengaged from the paper and are DIOVBdOLlb of the path thereof.

A number of modifications may be utilized. wherever desired so as to adapt my invention to individual purposes or to dilferent machines, it being understood that'l do not restrict) myself to. the specific arrangement illustrated and described except where set forth-lithe appended claims.
